We introduce a method for detecting the presence of time variation and instabilities in the parameters of predictive regressions linking noisy variables such as stock returns to highly persistent predictors such as stock market valuation ratios. Our proposed approach relies on the least squares...

We develop tests for detecting possibly episodic predictability induced by a persistent predictor. Our framework is that of a predictive regression model with threshold effects and our goal is to develop operational and easily implementable inferences when one does not wish to impose a priori...

The popular perception about economic reforms having benefitted only the richer districts of India between 1999/2000 and 2004/2005 is investigated. Using the spatial dynamics of district-level per-capita income it was found that income distribution did not change between the years examined. It...

In an effort to stimulate more attractive football, the international football association FIFA, has recently introduced the "sudden death" or "golden goal" rule for games going into extra time play. This paper analyses under which conditions, if any, the introduction of the sudden death rule...

We construct a zero net-worth uninformed "naive investor" who uses a random portfolio allocation strategy. We then compare the returns of the momentum strategist to the return distribution of naive investors. For this purpose we reward momentum profits relative to the return percentiles of the...

An optimal education subsidy formula is derived using an overlapping generations model with parental altruism. The model predicts that public education subsidy is greater in economies with lesser parental altruism because a benevolent government has to compensate for the shortfall in private...

In India, the popular perception is economic reforms have benefited the rich more than the poor leading to an unequal income distribution, as in Quah's twin peaks hypothesis. In this article we test this hypothesis by studying the spatial dynamics of income distribution. Using district-level...

This paper considers the dynamics of income distributional pattern in India. If reforms are pro-rich then would see emergence of twin peaks in the underlying income distribution function in India (i.e.clustering of the rich people, and clustering of the poor people). On the other hand, a uniform...
